How many times does your heart beat during your lifetime? round the answer to the nearest power of 10 and then express your answer as the order of magnitude. for instance, if your estimated answer is 3×105, enter 5. if your estimated answer is 8.7×105, you should enter 6 (rounding up to the next power of 10)?
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North
Hope this helps!
a. population growth is decreasing
so the population decreased by 24 because 3+3+8+10+2=26-2=24.
